Hello

[KafeLatte]

My project is Mitsubishi Lancer -91. My plan is to replace the original ECU to something better . Does anyone have experience with Frankenstein ECU with this car model ?

hello and welcome!

In what regard better than oem are you looking for? http://rusefi.com/forum/viewtopic.php?f=3&t=622&start=180 is very close to your engine I believe

Welcome along. I like the latte graphic.

Have you found the wiki? Just in case you have not, here's a link. http://rusefi.com/wiki/index.php?title=Manual:Hardware_Frankenso_board

Thank you very much , this is a good start for this project. I have an 4G15 model .
and I compared its connections 4G63 model .
I think that I need to make some changes to the circuit board .
for example
1. In the idle connector 4 - > 2 - pin
2. Ignition coil 4 - > 1 -coil
3. The circuit board dimensions and the holes to fit the original housing.
4. exchange 64- > 52 -pin connector .
5. and a lot of something else.

Have you notice the pile of W## via's right next to the harness connector? If you install a pile of 0R resistors, it works well for certain ECU's. If yours need some wires changed around on the harness pin out, instead of installing a 0R, you install a small wire that changes the pin out. You can see these jumpers in the graphic just below the picture on the wiki. You can see what I mean by looking at the picture on the status page. Notice that small rat's nest near the connector. Those wires are changing the pin out for that particular application.

I noticed you mentioned jumpers , and they make it easier to connect the different versions .
I use the connector has 52 - pin and I need to make changes to the connector footprint

Ah, different connector. See this tread, where @russian got an OEM ECU, removed the connector from that ECU, then made small PCB's which allowed the OEM connector to be re-attached. Then it allowed via's for adding wires, as well a 3D case was made.
